6 Claims.

My invention relates to siphons and particularly to rechargeable soda siphons. These siphons as heretofore made usually consist of a glass bottle or vase that is reenforced by a woven wire jacket or other metallic covering as in the well-known Sparklets' siphon. Each siphon has a removable siphon tube that extends nearly 1 to the bottom and is held in place at the top by a removable head. This head has a valve controlled discharge nozzle through which carbonated water from the siphon tube is discharged,

and a charging head which has a cooperating I bulb holder into which the carbon dioxide capsule is inserted for carbonating the liquid in the siphon. The glass vase forming the body of the siphon has a colored filling line marked on it which indicates the maximum level to which the siphon is to be filled with liquid before carbonating in order to produce the best carbonating of the liquid and the best safe working pressure. It sometimes happens through carelessness or inexperience that the person preparing the siphon for use fills it above the filling line. The

H result is that the increased volume of water is not properly carbonated and too high pressure is produced in' the. siphon. Also the glass vases, even though covered with metal reenforcement, are subject to breakage when dropped or struck sharply against a metal object or fixture.

, therefore, is to provide a filling or measuring tube within the siphon so that it can not be filled above a predetermined level.

Another obfiect is to provide means whereby the measuring tube may be quickly. and easily removed for cleaning the inside of the siphon.

Anotherobject is to. provide a safety device or vent so that the siphon can notbe charged if the filling tube is omitted.

Still another object of the invention is to provide an all metal siphon, thereby doing away with the glass vase.

Yet another object is to provide a metal siphon made in two parts detachably connected to- 15 gether, the upper part including the siphon head,

siphon tube and measuring tubebeing removable i ,asaunit.

Another object is to provide -a two part metal siphon with the measuring tube formed integral with or fixedly secured to the top removable section.

Another object is to provide a siphon having removable interchangeable siphon and shaker heads, whereby the body may be used either as a siphon or cocktail shaker.

The above and other objects and advantages of the invention are attained by the embodiments thereof that I have illustrated in the accompany- Fig. 3 illustrates how the siphon body may be 5" used with an interchangeable head as a. cocktail shaker.

Fig. 4 is an enlarged view, partly in section, of the siphon shown in Fig. 1. t

Fig. 5 shows-how the measuring tube may be 10 removed.

Fig. 6 shows how the gas may escape through the safety port if the measuring tube or its sealing washer is omitted.

Fig. 7 is a sectional view of a metal siphon with 15 the filling tube integral with the top section.

Fig. 8 is asectional view of a siphon having a glass vase with a measuring tube applied thereto.

Referring now to Figs. 1 and 4, the body l8 oi the siphon is made of metal and has a bottom ll 20 that is brazed or soldered in place so that the body is in efiecta single piece. The neck I! is exter-. nally screw-threaded at l3 to receive the siphon head I! which has a nozzle l5 controlled by the valve i6 and lever H. A charging head It opens into an expansion chamber I! in the-siphonhead l4 and is adapted to receive either the bulb holder 20 and carbon dioxide bulb 2| for charging the siphon or the closure cap 22 after the siphon has Among the objects of the present invention,

' measuring tube 25, which extends down in the siphon to the filling. level. The measuring tube 35 is enlarged or has a flange at its upper end the top of which lies substantially flush with the top of the neck and thelower side of which engages a gasket 25 to make a tight joint with the seat 23.

The measuring tube 25 is provided with some means, as lugs 21', adapted to be engaged by the I wrench 28 or other suitable tool so that it may readily be removed or inserted for any reason, as for cleaning or converting the siphon into a shaker.

The siphon tube 29 may be either glass or metal and extends nearly to the bottom of the siphon. It has a flanged head 30 at its upperend which engages the rubber gasket 3| and when the head.-

I4 is screwed into place it presses both the head 30 and gasket 3 I downward to form a tight joint with both the neck I2 and the end 24 of the filling tube to prevent the escape of gas.

-When it is desired to charge the siphon the head ll, gasket 3| and tube 29 are removed and 33 leading from the seat 23 to the outsideof the like tube 25.

neck, which will be left open by omission of the tube 25 and gasket 2% so that the gas will escape and dangerous pressure can not be built up in the siphon, as best shown in Fig. 6.

In Figs. 2 and 7 I show the siphon body made in top and bottom sections 34, 35, removably secured together by screw-threads 36, 31 and a packing ring 38. The same siphon head l4, siphon tube 28 and gasket 3| are used in these modifications as in Figs. land 4, but the measuring tube 39 may be integral with the top section 34, as shown in Fig. 7, or it may be removable The top section 34 is drawn in to provide a neck 40 (Fig. 7) that is screw-threaded to receive the head l4. While the tube 39 and section 34 are shown integral in Fig. 7, and are so described, they may originally be i'ormed as separate parts and brazed or soldered together to form a single piece, the junction of the neck 40 and tube 38 providing a seat 4i for the gasket II The lower end of the illling tube terminates substantially at the dividing line between the top and bottom sections, but, of course, the two parts may be separated at any other preferred level.

In Fig. 3 I have shown how my improved siphon may be used as a cocktail shaker. The shaker may be made by using the lower section 35 of the siphon shown in Figs. 2 and 7, and replacing the top section 34 with a plain section 34' closed by a removable shaker head 42. The head 42 may be secured to the section 34' in any suitable manner, but generally the section 84' has a screwthreaded neck the same as the neck 40 so that the shaker head 42 and siphon head N are interchangeable. closed by acap 43.

The siphon shown in Figs. 1 and 4 may likewise be used as a shaker. To thus convert the siphon, the head i4, siphon tube 28, and measuring tube 25 are removed and the shaker head 42 screwed on the neck l2 after the siphon body has been filled with the required ingredients. Likewise, both sections I4, ll of the siphon of Figs. 2 and 7 may be utilized in the shaker ii the tube a is made removable. I

In Fig. 8 I have shown a removable filling tube 44 adapted for use with a siphon having a glass vase or body 45 covered with a woven wire mesh 4 such as the well-known Sparklets siphon.

At its upper end the tube 44 is flanged as at 41 and is engaged by a rubber sleeve or packing 40 that flts snugly in the neck 4! of the vase 4B. A

metal neck .50 is secured to the siphon and is screw-threaded to receive the siphon head i4. Thefllling or measuring tube 4 extends down to the filling line of the siphon and prevents its being fllled too full. The tube 44 is easily removed upon remoyal oi the head l4 and siphon tube 2!.

Having thus described several forms that my invention may take, it wilbbe apparent to those skilled in this art that it may be embodied in many other forms and modifications, and! gasket engaging said The head 42 has a pouring spout as my invention all such that may'oome within the scope or spirit of my claims.
